T-shirts
are most often made of soft cotton that's prone to
distort during wear and washing. As casual items they don't
need the military style finish of formal shirts. knitwear also
needs gentle handling and soft finishing.

There aren't many
features on a t-shirt or on knitwear, often there won't even be a collar, so ironing is
a fairly simple process. Follow the method below, missing out the collar
if you don't have one.

Collar: As with
shirts a collar is the first thing ironed on a t-shirt. They
would normally be one piece and one layer, the type you can iron
from one side to the other with no problems, but there are some
which have a stiffening and two or more layers, meaning you have
to iron from the outside in (see shirt ironing).

Sleeves: are next and
will mostly be short, the difficulty being sorting the
distortion that happens because the fabric is so soft.
